Zusammenfassung:	A liquid discharge head includes a nozzle plate, a needle valve, a mover, a housing, and a sealing member. The needle valve includes a first part having a diameter and a second part having a diameter smaller than the first part. The second part has a leading end contactable with a nozzle to close the nozzle. The needle valve is movable between a position to open the nozzle and a position to close the nozzle. The mover moves the needle valve. The housing has a side wall, a bottom wall, and a liquid chamber communicating with the nozzle. The side wall and the bottom wall define a container containing the mover. The sealing member is disposed between the first part of the needle valve and the bottom wall to seal the container from the liquid chamber. The sealing member is deformable in accordance with the movement of the needle valve.
